Check kitting refers to an illegal practice of writing a check against a bank account. Check kitting is an intentional writing of a check for a value greater than the account balance from an account in one bank. Under this practice, a check is written from another account in another bank, with insufficient funds, with the second check serving to cover the non-existent funds from the first account.
The purpose of check kiting is to falsely inflate the balance of a checking account in order to allow checks that have been written that would otherwise bounce to clear. It is also known as kiting, or check flashing.
